After several unsuccessful attempts to make an appointment with other tree cutting firms, I heard about DNR Tree Service in Livonia and gave them a call. The owner promptly returned my call and in two days was in my back yard giving an estimate. A couple days later the whole crew showed up to remove a half dozen or so limbs from my black walnut tree. They removed all the limbs identified for removal and did a wonderful job trimming away small extending limbs to make for a nice rounded canopy. They cleaned up my back lawn and driveway to restore to their original condition and left without causing any reason for regrets. I am very pleased with the job done by DNR and for sure will call them again for my next trimming job. I have their number!
